Specification of Letters Patent.

Application filed January 17, 1913. Serial No. 742,750.

To all whom it may concern:

Be it known that I, JACOB HEINRICH, a subject of the German Emperor, residing at F iirth, Bavaria, in Germany, have invented certain new and useful Improvements in Apparatus for Composing and Decomposing Metal-Foil Molds or Forms, of which the following is a specification.

This invention relates to apparatus for composing and decomposing metal foil molds or forms of the kind in which the foils are taken off a pile of foils by means of a suction nozzle, and the object of my invention is to prevent the nozzle from taking Off more than one foil at a time. I attain that object by regulating or adjusting automatically the distance between the bottom plate carrying the pile of foils and the nozzle in such a way, that the distance is shortened by the thickness of one foil after each removal of such a one. This may be effected either by moving the bottom plate in the direct-ion to the nozzle or by moving the nozzle in the direction to the bottom plate. The thickness of the foils are, however, sometimes different, and to compensate the difl'erences thus brought about in the height of the pile, or, in other Words, the differences between the uppermost foil and the nozzle, whereby the accurate operation of the device is impaired, I have provided means for adjusting the device also by hand, as is all more fully described hereinafter.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the several views, and in which:

Figure 1 is a vertical section through one form of construction of my improved device, the section being taken in line AB of Fig. 3; Fig. 2 is a section in line C-D of Fig. 3, and Fig. 3 is a plan of said form of construction. Figs. 4, 5 and 6 respectively are similar representations relating to a slightly modified form of construction.

Referring to Figs. 13, 10 is a bar holding the nozzle 4, which is to be swung alternately over the pile to be composed and over that to be decomposed, and in one of these two positions said bar is connected with the right hand half, in the other position with the left hand half, of a horizontal arm 42 which may be vertically displaced in a guide 48 and the downward movement of which is limited by a stop 34. This stop consists of a threaded cheek which forms a support for the arm 42 when the nozzle shall be stopped on its downward way. The threaded cheek 34 is attached to a sleeve 48 and may be displaced by means of this sleeve upon a bolt 47 its threaded side meshes with a threaded spindle 44, which may be rotated in one or the other direction by a worm gear 45 46 so that the cheek is then moved up or down according to the direction of rotation. The connection between the threaded cheek 34 and the sleeve 48 is preferably effected by means of a spring 49 which constantly tends to press the male threads of one part into the female threads of the other. The worm gear 45 46 is generally driven by a pulley 50 rotated in its turn from any suitable motor by a belt, cord or the like. The pulley 50 sits loosely upon the shaft 51 of the worm 45 and is pressed against a collar 57 of this shaft by a spring or a poise 57 in such a manner that the shaft 51 is turned from the pulley 50 by friction. To increase the friction, a disk of leather, fabric or other suitable material, may be inserted between the disk 52 and the collar 57. To adjust the parts in question also by hand, I have provided a crank 53 aflixed to the shaft 51 of the worm 45.

The apparatus is operated as follows: The threaded cheek 34 is adjusted in such a manner, that the nozzle 4 contacts with the uppermost foil of the pile, that adjustment being effected by withdrawing the spring with the cheek from the threaded spindle and moving the former in the proper direction along the latter. Then the motor is started and the pulley consequently rotated. Owing to the friction between this pulley and the shaft 51 this latter is also turned, and so is also the worm gear 45 46, whereby finally also the spindle 44 is rotated. The threaded check 34 now moves slowly downward along the threaded spindle, and when the movement of the nozzle is stopped this action occurs just as much later as corresponds to the thickness of a foil. The speed of the pulley 50 and the pitch of the thread of the spindle 44 are such that the cheek 34 sinks just for the thickness of a foil after every two successive downward movements of the nozzle. If it is found after some time that there is no more a proper correspondence between the continuous movement of the cheek 3-1 and the diminution of the pile of foils, because a certain number of the removed foils have been thicker or thinner than the other ones, then a compensation may be effected by means of the hand-crank 53, so that the apparatus can be kept in this way in proper working order. I

In the form of construction shown in Figs. 46 the threaded cheek is secured to a vertically displaceable carrier 59 which takes below the bottom plate 54 of the frame 1 by means of vertical pins 58. The carrier 52 is guided by a column 55. The nozzle sinks always to the same depth, but the bottom plate is always lifted as much as corre sponds to the thickness of a foil, after the lowered nozzle has again been lifted, so that also in this way the proper relative position of the parts in question is maintained. Irregularities resulting from differences in the thickness of some foils may also in this form of construction be made up for by the hand crank, exactly as in the form of construction first described.

Having thus particularly described my invention what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus for composing and decomposing metal foil molds or forms, the combination, with a bottom plate adapted to carry a pile of the foils and a nozzle adapted to remove the foils singly from said pile, of

a holder for said nozzle, a threaded cheek forming a support for said holder, a thread ed spindle meshing with said cheek, and means for rotating said spindle, for the purpose as described.

2. In an apparatus for composing and decomposing metal foil molds or forms, the combination, with a bottom plate adapted to carry a pile of the foils, and a nozzle adapted to remove the foils singly from said pile, of a holder for said nozzle, a support for said holder, a threaded spindle meshing with said support, a spring attached to the latter, a holder for said spring, and means for rotating said spindle, substantially as described.

3. In an apparatus for composing and decomposing metal foil molds or forms, the combination, with a bottom plate adapted to carry a pile of the foils, and a nozzle adapted to remove the foils singly from said pile, of a holder for said nozzle, a support for said holder, a threaded spindle meshing with said support, a spring holding said support and said spindle in mesh with each other, a worm gear forming part of the driving gear for rotating said spindle, and means for rotating said gear by friction, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
